(35 cards)
what vessel brings venous blood up from the liver to the right atrium
Inferior vena cava
Superior vena cava brings venous blood where?
down from the head and upper extremities to the right atrium
Venous blood flows is:
From right atrium to tricuspid valve to right ventricle through pulmonic valve to pulmonary artery to lungs
where is the blood oxygenated?
lungs
Fresh blood flows is:
Through pulmonary veins to left atrium through mitral valve to left ventricle through aortic valve into aorta
what does the aorta do?
Aorta delivers oxygenated blood to the body
Cardiac cycle has how many cycles?
has two cycles– diastole/systole
what happen in the diastole cycle?
ventricles relax, fill with blood
what happens in the systole cycle?
heart contracts
blood pumped from ventricles &
fills pulmonary and systemic arteries.
where can you hear S1?
S1 (normal) – can be heard all over pericordium,
*loudest at APEX
where can you hear S2?
S2(normal) – can be heart all over pericordium,
*loudest at BASE
where can you hear S3?
S3 ( normal or abnormal)- can be heard at apex or left lower sternal border
When can S4 occur?
S4 (could occur in adults older than 40 without cardiovascular disease, especially after exercise.
What is the process to assess heart sounds during auscultation over precordium?
Auscultate from base of heart to apex in zig zag formation over four valve areas (aortic, pulmonic, tricuspid, mitral)
What does heart murmur sound like?
Gentle, blowing, swooshing sound heard on the chest wall
What are the characteristics of heart sounds?
Frequency
Intensity
Duration
Timing
The heart pumps how many liters of blood per minute throughout the body in a resting adult?
4 – 6
where is the carotid artery located?
Carotid artery is located between the trachea and the sternomastoid muscle
what should the carotid artery feel like on palpation?
Should feel soft and pliable
During auscultation what can a bruit sound like?
heard as blowing or swishing sound
how would a bruit sound differently when atherosclerosis worsens?
Bruits get louder as atherosclerosis worsens,
when totally occluded bruit will disappear
what is the major cause of stroke?
Major cause of stroke is carotid artery stenosis
what is hemorrhagic stroke often related to?
to hypertension
Ischemic stroke often related to?
atherosclerosis
